Explanation:

Step1: Identify base and height

The base is $DF$, and the height is $GE = 6$ units.

Step2: Use triangle - area formula

The area formula of a triangle is $A=\frac{1}{2}\times base\times height$. Here, we can consider $DF$ as the base and $GE$ as the height. The area $A=\frac{1}{2}\times DF\times GE$. Although we are not given $DF$ directly, we don't need it as we can use the fact that the area of $\triangle DGF$ with height $GE$ and considering the base - height relationship. Substitute the values: $A=\frac{1}{2}\times (DG + GF - EF + DE)\times GE$. In fact, we can also use the formula with the given height $GE$ and assume the base formed by the line segment related to the triangle's structure. The area $A=\frac{1}{2}\times (DG + GF - EF + DE)\times GE=\frac{1}{2}\times(6.5 + 10)\times6$. First, calculate the sum inside the parentheses: $6.5+10 = 16.5$. Then, $A=\frac{1}{2}\times16.5\times6=16.5\times3 = 49.5$ (This is wrong. The correct way is to use the height $GE$ and the base formed by the line on which $GE$ is perpendicular.
